Question

if the length, breadth and height of a cuboid are 8cm,6cm and 4cm respectively. find the total surface area of cuboid

Answer 1

Answer:

Step-by-step explanation:

Surface Area (TSA) of cuboid =

376 cm²

Step-by-step explanation:

Given -

Dimensions of cuboid :-

Length (l) = 10 cm

Breadth (b) = 8 cm

height (h) = 6 cm

to find -

Surface area (T.S.A.) of cuboid

solution -

T. S. A. of cuboid = 2(lb+bh+lh)

= 2 × {(10×8)+(8×6)+(10×6)} cm²

= 2×(80+48+60) cm²

= 2×188 cm²

= 376 cm²

Hence surface area of cuboid = 376 cm².

extra information -

Total Surface Area (TSA) of cuboid = 2(lb+bh+lh)

Lateral Surface Area (LSA) of cuboid = 2(lb+bh) or 2(l+b)h

TSA of cube = 6a²

LSA of cube = 4a²

in this exercise you have to use these formulas.

Answer 2

Answer:

=> The total surface area of cuboid 208 $cm^{2}$

Step-by-step explanation:

Given that:-

The length of a cuboid is 8cm

The breadth of a cuboid is 6cm

The height of a cuboid is 4cm

To find:- The total surface area of a cuboid

For calculating, T.S.A of cuboid we have to use the formula:

=> T.S.A = $2( lb+bh+hl)$

Now plug all the values in the formula:

=> T.S.A = 2 ( 8 $\times$ 6 + 6 $\times$ 4 + 4 $\times$ 8 )

             = 2 ( 48 + 24 + 32 )

             = 2 ( 104 )

             = 208 $cm^{2}$
